Hey guys got to the point of firing up my 6.0 in my 92. It cranks right up but only runs for a second. Is this just the vats? I knew i would need to get it re flashed but just wondering if anything else could cause it to shut off. Thanks in advance guys.
More than likely VATS.

ok thats what i was thinking. A guy i work with has a buddy who can turn it off and tune the computer. Ill try and get him to hook to it and go from there. Im so ready to drive this thing!! Its been down for too long. lol but thanks for the speedy reply!!
No problem I had the same thing on my 81 when I first started it.
I had mine turned off before I ever tried to start it. I didn't want to chase an issue if it was just the vats
well i got the obd2 plug wired up today so hopefully i can get it fixed this week. I checked the fuel pressure today and the gauge was pegged out over 100 psi on the rail. Is this normal? I have a 2002 vette filter and walbro 255 inline with the returnless rails. I just put 12 volts to the pump. Im gonna wire in a relay and wire it to the ecm tomorrow.
You have something way wrong. Should be 58 at the rail with a vette filter.

yeah i thought it was supposed to be 58-60 on the rail. i wired the pump to the computer..ill have to check the pressure tomorrow again.
Sounds like you may have the regulator plumbed backwards. The 3/8 line should be from the pump and the 5/16 returns to the tank. The end with only one fitting goes to the engine.
